RESISTANCE MEASURING INSTRUMENTS
D07E RUGGED DIGITAL MICRO OHMMETER FOR LOW RESISTANCE MEASUREMENT
The DO7e is a very rugged yet compact and portable digital
key feature
micro ohmmeter for the measurement of low resistance. Using a
True 4 wire measurement eliminates lead resistance
■
6 push button ranges 6 milli ohm to 600 ohm
■
rechargeable sealed lead acid battery with built-in charger,
DO7E
Resolution 1 micro ohm on 6 milli ohm range
■
the DO7e is capable of measuring with a current of 10 Amps on
Auto ranging
■
the lowest range. The DO7e has been designed with the latest
10 Amp measuring current on lowest range
■
0.8'' LED Display daylight viewable
■
solid state and microprocessor techniques to ensure the very
Input protection up to 415 Volts rms
■
best in measurement, reliability and features. Automatic range
Forward and reverse current measurement
